The 2014 Chevrolet Silverado completed more than 12.5 million miles of testing before General Motors put the vehicle on sale this past Summer.
GM says its fleet of Silverado test vehicles completed more than 4 million miles of combined durability testing and 8.2 million miles of real world driving before being sent into production in Silao, Mexico, Fort Wayne Ind. and Flint, Mich. The testing was done in the scorching deserts of Arizona, the frozen grounds of Kapuskasing Ontario, and of course GM’s own test facility.
The truck went through the standard series of torture tests at GM’s Milford Proving Ground, including the Belgian Blocks rough road simulator, grit trough off road simulator, and high speed driving. An uneven road paved with cobblestone “Belgian Blocks” tests the forgiveness of the suspension and durability of the components. The grit trough helps engineers fully understand where the trucks need sealing to protect wheel bearings and key suspension points, a necessity for an off-road vehicle.
“It takes refinement and testing to build the strength that our customers expect and rely on from their trucks,” said Phillip Hubler, GM vehicle system engineer. “Our philosophy with the 2014 trucks was to improve what needed to be improved and leave alone what was already considered world class.”
Durability improvements to the 2014 Silverado over the outgoing model include a high strength steel frame to prevent against cracking under heavy loads, A 4 wheel diskbrake system with Duralife rotors offering double the service life and an anti chip coating on the lower body to protect from stones or gravel.
